When my house was built, the gas cooktop was vented out through the slab by an 8" PVC pipe which was just left as an open bricked in hole in the ground. I covered it with a metal chimney cap to keep pests out, but every winter the cold air blows in through the downdraft on the stove.This 8" damper slid right into the PVC pipe perfectly creating an excellent seal and opens properly when the down draft exaust fan turns on. When the fan stops the damper shuts tight and no more drafts in the kitchen.

I installed this in the ductwork from a bathroom fan that I recently put it that has a damper that does not seal very well. Since my duct run was mostly horizontal this damper would not close 100% of the time and would let a small draft in. I had to take the damper apart and flip the spring around a put a half turn on it to help close the damper doors more securely. I think my bath fan is only an 80 cfm unit it still opens the damper fine. If this is installed in a vertical orientation and gravity would help close it I think it would work fine. Other option is to find a slightly stronger spring.

Good for horizontal or vertical use

Comments about RSK Series 4" Duct Backdraft Damper:
We installed a through the wall fan and used this backdraft damper. Because it has a spring to assist in closing the damper, it works in the horizontal orientation. This works very well and it avoids a cold air draft coming back into the house when the fan is off.
Bottom Line Yes, I would recommend this to a friend

Just what I needed - fast shipping
Used for additional back-draft protection for Range Hood and bath exhaust fan.I love this is slips inside duct work. The price was very reasonable.The shipping was so fast I couldn't believe it - less than 24 hours in my case.
Good Backdraft damper

Comments about RSK Series 5" Duct Backdraft Damper:
IT IS GOOD FOR KEEPING COLD AIR FROM GETTING IN THROUGH THE RANGE HOOD.Does not seal real good, or would have given 5 stars.
i would buy this product again
Comments about RSK Series 12" Duct Backdraft Damper:
could use a crimp one end
Better than Most
from Woodbridge, NJ
Better than most for backdraft protection installed at the output of a bathroom ventilation fan. If used in a horizontal duct, be sure to turn it so that the rod the two flappers pivot on are in a vertical position so that the upper flapper does not have to fight gravity to close fully.
Cheap, wellmade, works
What else can I say. I was getting tons of cold air back thru my Microwave/Range hood combo. Installed in attic and no more cold air!
PRODUCT NEEDS BETTER SPRINGS
Comments about RSK Series 10" Duct Backdraft Damper:
HAD TO INSTALL SCREWS IN DUCT WORK TO PREVENT THE DAMPER FROM FLOPPING OVER TO THE OTHER SIDE.ONCE I MADE THIS EASY ADJUSTMENT THE DAMPER WORKED JUST FINE.
